After broadcasting the ancient times live, I handed the system over to the state.

[It seems that going overtime is a tradition, no matter where you are or what time it is. Wiping away sweat.]

[I think the teacher must have really liked this student, otherwise they wouldn't have taken his work to their grave.]

[When I bring it home, I'll definitely tell my family with a big smile.]

[That dreaded homework!]

[Bu Tianshou: You should call me Ancestor Tianshou!]

……

Under the canopy, Bu Tianshou, who finally had a day off and didn't have to copy books, saw his homework, his doggerel, and his messy handwriting projected onto the canopy. Listening to his family's teasing, the mischievous Bu Tianshou actually became a little shy.

"This is terrible! Now everyone knows I talked about Mr. [Master] behind his back!" Bu Tianshou was almost in tears, but when he saw that those who talked about Mr. [Master] had taken his belongings to their coffins, he became even more heartbroken. "I don't want Mr. [Master] to die—"

He wanted to go home early and didn't want to copy books, but he also didn't want to die first!

The next day, Bu Tianshou ran to his husband's door and burst into tears. His husband sighed, smiled, and shook his head, "How about copying more?"

"...?!?!?!" Bu Tianshou immediately wanted to run away; the master was too terrifying!

In the end, the teacher caught him, and he said with a smile, "You always have to practice your handwriting to be better. Also, write those few wrong words a few more times!"

Thus, Bu Tianshou was forced into a frenzy of practicing calligraphy.

……

"So this is how you become famous? And have your name remembered for eternity?" Many people thought this after seeing the example of Bu Tianshou.

And then there was that Feng Menglong we discussed before. Wasn't he someone who did something to the extreme, and was remembered by the people, thus earning a place in history?

And that Wen Bacha, his lyrics are also passable... These people are good, why aren't they good?

Some people seeking fame began to take action.

Some pragmatic people simply smiled and continued with their own business.

Many people still use Bu Tianshou's example to inspire their descendants.

However, this 'incentive' is a different kind of 'incentive'.

Zhu Yuanzhang was tired of seeing his sons Zhu Shuang and Zhu Wang, those roughnecks. Perhaps some people would joke that Bu Tianshou was not as good as the child on the sky in his eyes.

"Get out, get out! You guys better write your characters properly, they're like dog scratches! If future generations see your handwriting, we'll be too ashamed to show our faces."

They never expected that even after getting married, the old man would drag them back to practice calligraphy.

People from later dynasties who saw the Analects of Confucius with Zheng Xuan's commentary on the sky were overjoyed and quickly copied it down.

Zhu Qinggu also found it quite amusing; there was quite a bit of homework from over 1,300 years ago!

She quickly moved on to the next video, and the people under the canopy soon focused their attention again.

Soon, everyone's attention was drawn to it.

How would you achieve salt freedom if you traveled back to ancient times?

Salt! A person cannot live without salt; in fact, they might die. Therefore, salt is an essential commodity.

Salt has always been controlled by the government, and there is also some smuggled salt, but this salt is really too expensive!

Many households use vinegar cloths or salt cloths, but even these are not affordable for every family.

Salt was indeed a matter of great importance to the national economy and people's livelihood, so when Tianmu's video was released, it was like a thunderclap in front of the ancients.

"Write it down quickly, write it down quickly!" Countless people hurriedly picked up pens and paper, even using stones and dirt around them to write it down.

Ying Zheng stared intently at the sky.

Liu Bang quickly had someone write it down.

Meanwhile, Liu Che's entourage had been recording everything, and now several more people had been added to the recording team, fearing that there was too much information being presented on the screen for them to keep track of.

Liu Xiu also paid close attention.

As rulers, Liu Bei, Sun Quan, and Cao Cao were extremely perceptive about matters that affected the people's livelihood.

Emperor Wen of Sui also stared intently at the sky, knowing that the Sui Dynasty had also ended after only two generations. Moreover, the Emperor Yang of Sui revealed on the sky was actually his second son, Yang Guang. They quickly abandoned their idea of ​​deposing the crown prince.

Actually, Yang Yong isn't much better off. It's uncertain whether they can have another child; if not…

They all had the absurd idea of ​​going to the Li family to snatch their son.

Li Shimin would naturally not miss such a major event concerning the country.

The same applies to Li Zhi and Wu Zetian.

Li Longji was still young, and he was working hard to govern the country. The Tang Dynasty was gradually entering a golden age, and he could not afford to be indifferent to such an important matter.

Not only the emperor, but also court officials, common people, and even children among the common people were all eagerly waiting.

"my country's salt is mainly divided into sea salt, lake salt, and well/mineral salt."

The main distribution areas of these three salts are marked on the map.

Everyone, please write this picture down immediately.

"Well and mine salt production is simple; as long as you can control the salt mine, you can directly obtain high-quality crude salt if the sodium chloride content is high."

"However, we also know that in ancient times, these salt mines were usually occupied by the government or private individuals, and you wouldn't get a chance. You'd typically have to go to the seaside or the edge of a salt lake."

They didn't understand what sodium chloride was, but they still wrote it down as usual.

And then there's the salt from the sea... Is salt from the sea poisonous? Is it really safe to eat?

If there were a way to make this sea salt non-toxic, wouldn't they have a salt supply they could use for a lifetime?!

At this moment, some people who held salt mines hoped that the sky would tell them quickly, but they also didn't want the sky to reveal the method of salt production. If everyone knew, wouldn't the value of the salt in their hands plummet?

If only this canopy could speak to them alone, without letting others know its secrets.

But their ideas couldn't change the sky.

Tianmu continued speaking.

"The purification of crude salt mainly involves dissolving, filtering, and crystallizing."

"To make sea salt, salt pans need to be created along the coast. Seawater is introduced into the salt pans during high tide, and then the water is evaporated by the sun. The resulting crystals are coarse salt."

Many people know that you can get coarse salt by exposing it to the sun, but this kind of coarse salt is poisonous!

Some people on the beach stared intently at the sky, wondering what steps they would need to take next.

"At this stage, the coarse salt still contains many impurities and cannot be eaten directly; it needs to undergo a series of processing steps."

"The first step is to remove small particles like mud and sand. Coarse salt is dissolved in water to filter out the mud and sand. Next, it's evaporated, with the brine constantly stirred to ensure even heating. This produces crystal salt, which still contains small amounts of magnesium chloride and potassium chloride, but this is sufficient to meet basic requirements."
